If you're looking for something different to do.....
I think this is a great thing to do if you're too chicken to do the real thing like I am. We paid for the "family discount" since there were 5 of us and then I used some discount from Yelp awhile back. Also got the video as a cheesy souvenir for us. Dad paid so not sure how much it was, but I'm sure it's cheaper than jumping out of a plane!
They supply the windsuits, gloves, and helmets. I recommend wearing comfy clothes underneath and I wouldn't wear a dress or skirt. Then you watch some instructional video on what to do while you're in the wind tunnel. But you'll have someone from staff directing you on what to do anyways.
Basically the instructor will be in the wind tunnel with you at all times. If you go with a group, the rest of you will be chilling to the side while staff works with one of you. This was a lot of fun and I had a good laugh watching my sister and brothers flop all over the place in the beginning. I looked like the biggest dork trying to get some wind. But after our second or third try we were flying in the air and our instructor was spinning us around. Our guy was hilarious, showing us tricks too and telling us about the celebs that have gone here. I guess Kendra from Girls Next Door did it and it was amusing to see everything but her fake boobies move in the wind tunnel. Haha.....Good times, I'd do it again!
